MACHINE FOR STRAIGHTENING THE wEEr-rHREens oE'rEX'rILErI cE GOODS.

To all w ham it may concern Be it known that I, EMIL HUB R, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvement-sin Machines for Straightening the Weft-Threads of Textile Piece Goods, of whichthe following isa specification. I

This invention relates to an improvement in the machine described and claimed in my Patent. No. 1,326,057' granted December 23,.

1919, on a machine for straightening the justment while its other bearing swivele'd;

It has been found in practice that itis often desirable to change the relative positions of the rollers and their angles witheach other to a greater extent than was possible with the old machine. With this idea inview, it was conceived that by having all the bearings of all the rollers capable of universal adjustment, that more delicate and accurate set of the rollers for any particular piece of work could be obtained.

An object of my invention is to accomplish the accurate adjustment of the rollers to any desired angle or position so that my machine may be adapted to successfully perform its functions under all conditions of use.

Another object of my invention is to provide a machine in whiclrthe construction is simple and light andyet combines great strength, with the additional feature that it-f may be attached to any convenient overhead structure such as is commonly used in cloth handling machinery..

With these and other objects in view which may be incident to the improvements, my invention consists in the parts and com-V binations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my inventionmay :be varied in their proper tions and arrangement without depart1ng l Application filed March'12,1920.

In order. to make my invention more clearly understood, I have shown in the accompanying drawings, means for carrying 'itin to practical effect without limiting the improvements in their useful applications 'to the particular constructions, which for the purpose of explanation have been made the subject of illustration.

Figure 1 is a side elevation of one form of a weft tendering mechanism embodying my invention. Fig. 2 is a top view'of the weft: tendering mechanism shown in Fig. 1. Fig.

3 is an 'end elevation of the formof weft tendering mechanism shown in Fig. 1. Fig 4: is a detail partly in elevation and partly I in cross section of the swiveled bearing and means for movement of the same. Fig. 5 is a detail partly in elevation and partly in cross section of'the mechanism for moving the swiveled bearing both vertically and horizontally. Fig. 6 is a cross sectional view taken through line 6- 6 of Fig.5.

The frame for supporting the rolls consists of side bars 1 and2 formed preferably of angle iron. Through the upperside of an angle iron are drilled holes 3 whereby the side bars 1 and 2 will be screwed, bolted or riveted'to any convenient supporting struc-,

Bolted to' the downwardly projecting and 7 and 8 respectively. To one end of the side bar 1 and to the end of strut 6, that is not bolted to the side bar 1, is bolted an upright 9. Correspondingly at the other end of the side bar land the free end of strut' 5 is bolted an upright 10. Likewise to the side bar 2 and to the strut 7 is bolted an upright 11, and to the side bar 2 and the strut 8 is bolted an upright-12. Uprights 9 and 11 are horizontally connected by guide are of square rolled steel and not only serve the purpose of formmga strong frame bars 13 and 14 whichfare suitably bolted V 'therethrough. The guide bars. 13 and 14' 'structurebut act as guides for the movable structure supporting the rollers to be later described. The uprights 10 and 12 are also connected by guide bars 15 and 16 which same functions as haspreviously been explained in regard to guide bars 13 and 14:.

- serve the same purpose and perform the.

16 would be a very expensive undertaking However, by maklng the aperture through 16 larger than is necessary and pouring in Babbitt metal, an accurate and efficient bearing is made at small cost. L kewise the reciprocating supports 16 are adapted to be driven by a traveling screw later to. be described and where they have their surfaces of contact with the traveling screw, Babbitt metal is again employed as indicated at 18. A screw is set in place with either right or left hand threads and Babbitt metal is poureda'round the same. The surface of contact of this Babbitt metal 1.8 with the traveling screw is less than half a circumference of a circle. This bearing metal is retained in, place and prevented from slipping by having the hard metal of the member 16 slightly indented or reamed out as indicated at 18'. The hot babbitt flows into these recesses and upon. cooling the bearing surface is lockedfi'rm'ly in place.-

As clearly shown'in Fig. 3, the support 16. is formed with supporting webs 19 (see Fig. 6 for detail of cross section). The purpose of these webs is to give added strength and rigidity to the member 16 and to equal ize the strains to which it is subjected;

Through the center of the member 16 is bored a cylindrical hole from its top down to a point just above the Babbitt metal 17. Because of the size of the cylindrical hole and the confi uration of the'reciprocating support, there is left an air space as indicated in Figs. 3 and 5. The walls 20 of this cylinder are ada Jted to serve as guides. At the top of the support 16 is a screw support 21 firmly bolted in place. Within the cylindrical guides 20 is adapted to reciprocate a cylindrical plunger 22 provided at its top with a screw threaded aperture 23 into whichis screwed a screw 24. is adapted to be fastened in place by any of the well known systems such as by putting sal-ammoniac on'the threads and allowing them to rust tight or by drilling through plunger 22 and screw 2% and inserting pin. At the other end of the screw 24 1s a bushing 25 screw threaded'to accom-- .modate the convolutions of the screw 24.

The screw 24 hand wheel 27 is keyed to the bushing 25 by means of a key 28. In the case of the upper rolls the bushing 28 lies above the plate 21 and the hand Wheel so that the collar 26 takes the downward strain and supports the screw 24. In the case of the lower rolls, the collar 26 is similarly, locked to turn integrally with the hand wheel but is located above the plate 21 so that it may bear a downward pressure.

Thecylinder 22 is bored out to form a shell as indicated at 29 and a seat 29 of conical cross-section corresponding to the shape of the bit. at its lower end (see Fig. 4) there is provided an annular plate 30 which closely fits the interior of the cylinder 29 and is keyed in place by a pin 31. port the rolls A and B are providednear their extremities with a sphere 33 adapted to fit within the interior of the cylinder 29 and forming a universal joint. The bearing surfaces are formed by the plate 30 and the conical bearing surface 29. Through the cylinder 29 aredrilled holes 3 L passing from one side through to the other and through which are adapted to pass the shafts 32.

The size of the apertures 34: is such that the rolls may be rotated to any convenient de sired angle asindicated in dotted lines in Fig. 4L.

Passing through the uprights 9 and 10 and 11 and 12, parallel to and midway between the guide bars'are shafts 35 carrying over a portion of their length 2-way screws 36 which are adapted. to be turned by means of convenient hand wheels 87. Bearing against the screw threads and in engagement therewith are the bearing surfaces 18'previously described. 'It is to be understood that the bearing surfaces 18 in the case of the upper rolls are adapted to engage with the right handscrew threads, whereas those of the lower rolls are adapted to engage with the left hand screw threads or viceversa.

By means of hand wheels 87 the reciprocating supports 16 may be made to assume any desired position upon the guide bars. It will be understood that the upper reciprocating support moves in one direction while the lower one is moved in an opposite direction so that the rolls may be made to assume any of the positions shown in dotted- That is to say the rolls maylines in Fig. 3. be directly one above another or may be at the extreme opposite positions permitted by the length of the screw thread 36 and the construction of the machine. Likewise the ends of the rolls may be raised or lowered at will by operating the hand wheels 27 which by turning bushings 26 raise or lower the pistons 22 that carry with them the ball and socket joints in which turn the shafts 32 of the rollers A and B.

Shafts 32' which supare held very steady.

cating supports 16,v ar'e'held in their positions and may be subject to considerable;

strain without suffering displacement.

Likewise by reason of web supports 19,the

plates 21 upon, which comes the greater portion of the strain ofsupporting the rollers Itwill be apparent tothose skilled in the art that a very compact and strong construction is achieved by my invention. There is small danger of'distortion due to normal strain and there will be but little vibration because of the sturdy construction of the frame and the reciprocating supports. Any desired angle between the rollers or any desired position of the rollers may be obtained in my machine. The bearings of the shafts of each of the rollers are movable at their ends to any desired position within the plane of the reciprocating supports hence a very efficient and extremely flexible adjustment is achieved. My machine will, because of its adaptibility to any conditions of ordinary use, increase the number of firsts and decrease the number of seconds and will perform the labor usually performed by several skilled workers'.

While I have described but one embodiment of my invention it is apparent that many modifications may be made thereunder by those skilled in the art without departing from the spirit thereof and I desire therefore that my invention belimited only as set forth in the appended claims or by the showing of the prior art. 1
